Goldman Sachs spokeswoman Andrea Raphael said the financing comes in the form of a bond that can later be converted into stock when Uber goes public. Goldman said the deal completed a few days ago is one of the largest private convertible debt offerings on record. It was earlier reported by Bloomberg News.

Last month, San Francisco-based Uber raised $1.2 billion in financing that valued the company at $40 billion. That puts it in the ballpark of public companies such as DirecTV and Kraft Foods.

Uber is working on expanding internationally, though it faces regulatory hurdles and opposition from traditional taxi companies in many countries.
